IS sound probleme 100 2.8 L IS USM Macro with my EOS 5D MK III ? [SOLVED]

[Chris GER]

Hello,

I have observed the following effect when I use the 100 2.8 L IS USM Macro with my EOS 5D MK III.
If I have start the IS, the IS motor sound is VERY present, but after one minute (continuous operation),
sometimes longer, this sound disappears. (see this MP3: http://www.space-observer.de/CR/5DMK3.mp3)
If I use the same lens with my EOS 50D  the IS sound is always very quiet.
(see this MP3: http://www.space-observer.de/CR/50D.mp3) .

Has anyone ever notice this effect with the 100 2.8 L IS USM Macro in combination with the EOS 5D MK III ?

I haven't heard any noises in the same setup; 5D3 & 100L Macro. But then again I wasn't looking for it.

Hello,

Typical noises of that lens. Mine does the same mated to my 5D MkIII. It is part of the Hybrid IS system.

Thanks for your request !

How is it at your setup, did you hear a present IS sound, even if the camera does not move, and disappears this sound with time (continuous operation) ?
